# databroker Connects an agent to MossForge DataBroker for UK MOT history and reliability data. Calls are paid in USDC on Base, with no API keys or subscription. - MCP server · `type=mcp` · Claude Code, Codex, Cursor, GitHub Copilot, Windsurf (Devin Desktop), Cline, Zed, Gemini CLI - Author: mossforge - License: MIT · policy=link-only · description only; the file stays with the author - Source: https://github.com/mossforge/databroker/tree/HEAD/mcp-server - Updated: 2026-08-30 - HTML: https://affpapa.org/en/nevibecode/mcp/databroker ## What it does The server starts with `npx -y @mossforge/databroker-mcp` and exposes several tools. `databroker_discover` lists the enabled datasets and their USDC price per call, while `databroker_meta` returns staleness, TTL and source details without charging. `databroker_fetch` pulls one datapoint by key. `databroker_batch_create` takes up to 100 keys from a single dataset as one job under one payment, and `databroker_batch_status` polls that job. Every paid tool quotes first. Money moves only on a second call carrying `confirm: true`, and `DATABROKER_MAX_USDC` (default 0.50) rejects anything priced higher before payment. On clients that advertise MCP elicitation, the server asks the human to approve the exact URL and amount itself; Claude gained this in v2.1.76. Elsewhere the check is skipped and the `confirm: true` flag plus the cap are all that stands between the model and your wallet. You need a funded wallet on Base mainnet. In `raw` mode the private key sits in `DATABROKER_WALLET_KEY` and signs locally. The `cdp` mode pays through a Coinbase-managed wallet and wants `CDP_API_KEY_ID`, `CDP_API_KEY_SECRET` and `CDP_WALLET_SECRET`, plus an installed `@coinbase/cdp-sdk`. In raw mode the key is as safe as the process environment around it, so a fresh wallet holding a small balance is the sane choice. ## Requirements - Needs: Node.js (commands run via npx) - Environment variables: `DATABROKER_BASE_URL`, `DATABROKER_SIGNER`, `DATABROKER_WALLET_KEY`, `CDP_API_KEY_ID`, `CDP_API_KEY_SECRET`, `CDP_WALLET_SECRET`, `DATABROKER_MAX_USDC` — keys and tokens: ask the human for the values, never commit them or put them in shared files. ## Install ### Claude Code (native platform) **Platform CLI** ```bash claude mcp add databroker -e DATABROKER_BASE_URL= -e DATABROKER_WALLET_KEY= -e CDP_API_KEY_ID= -e CDP_API_KEY_SECRET= -e CDP_WALLET_SECRET= -- npx -y @mossforge/databroker-mcp ``` Replace <…> with your own values. 2 more environment variables are in the server README ### Codex **Platform CLI** ```bash codex mcp add mcp-server --env DATABROKER_BASE_URL= --env DATABROKER_SIGNER= --env DATABROKER_WALLET_KEY= --env CDP_API_KEY_ID= --env CDP_API_KEY_SECRET= -- npx -y @mossforge/databroker-mcp ``` Replace <…> with your own values. 2 more environment variables are in the server README ### Cursor **Config file** File `.cursor/mcp.json`: ```json { "mcpServers": { "mcp-server": { "command": "npx", "args": [ "-y", "@mossforge/databroker-mcp" ], "env": { "DATABROKER_BASE_URL": "", "DATABROKER_SIGNER": "", "DATABROKER_WALLET_KEY": "", "CDP_API_KEY_ID": "", "CDP_API_KEY_SECRET": "" } } } } ``` Replace <…> with your own values. 2 more environment variables are in the server README ### GitHub Copilot **Config file** File `.vscode/mcp.json`: ```json { "servers": { "mcp-server": { "type": "stdio", "command": "npx", "args": [ "-y", "@mossforge/databroker-mcp" ], "env": { "DATABROKER_BASE_URL": "", "DATABROKER_SIGNER": "", "DATABROKER_WALLET_KEY": "", "CDP_API_KEY_ID": "", "CDP_API_KEY_SECRET": "" } } } } ``` Replace <…> with your own values. 2 more environment variables are in the server README ### Gemini CLI **Platform CLI** ```bash gemini mcp add -e DATABROKER_BASE_URL= -e DATABROKER_SIGNER= -e DATABROKER_WALLET_KEY= -e CDP_API_KEY_ID= -e CDP_API_KEY_SECRET= mcp-server npx -y @mossforge/databroker-mcp ``` Replace <…> with your own values. 2 more environment variables are in the server README ## When to use it - check a car's MOT record before agreeing to buy it - see whether the odometer reading matches the test history - fetch a hundred keys in one job and one payment - inspect data freshness and source without spending - keep a single call under a hard spend cap ## Example prompts - Should I buy a 2018 Golf with reg `AB18 CDE`? Look up its MOT history and tell me if the mileage is plausible. - List the datasets that are switched on and what each call costs. - Run a batch over these 50 registration numbers and show me the total quote before paying. ## Similar - [Pyrimid Protocol](https://affpapa.org/en/nevibecode/mcp/pyrimid-protocol.md) — MCP server - [x402](https://affpapa.org/en/nevibecode/skills/x402.md) — skill · 1300 installs - [basebalance.cloud — x402 RPC & MCP gateway](https://affpapa.org/en/nevibecode/mcp/basebalancecloud-x402-rpc-mcp-gateway.md) — MCP server · ★ 7548 - [mcp-x402](https://affpapa.org/en/nevibecode/mcp/mcp-x402.md) — MCP server · ★ 274 - [payanagent](https://affpapa.org/en/nevibecode/mcp/payanagent.md) — MCP server · ★ 6 - [BotsRated (beta)](https://affpapa.org/en/nevibecode/mcp/botsrated-beta.md) — MCP server --- NeVibeCode on affpapa.org.
